Given the supported architecture list only contains 64-bit targets, this happens
to work out the same as the supported targets in most cases but may matter for

For other targets, the practical effect is that the test names contain the

The behavior of CTRL+C is slightly more erratic than one would like. CTRL+C in the middle of execution of Python code will cause that execution to be interrupted (e.g. time.sleep(1000)), but a CTRL+C at the prompt will just cause a KeyboardInterrupt and not exit the interpreter - worse, it will only trigger the exception once one presses ENTER.

llvm-cov: Fix reading gcov data that does not have function names
In order for recent gcov versions to read the coverage data, you have
to use UseCfgChecksum=true and FunctionNamesInData=false options for
coverage profiling pass. This is because gcov is expecting the
function section in .gcda to be exactly 3 words in size, containing
ident and two checksums.
While llvm-cov is compatible with UseCfgChecksum=true, it always
expects a function name in .gcda function sections (it's not
compatible with FunctionNamesInData=false). Thus it's currently
impossible to generate one set of coverage files that works with both
gcov and llvm-cov.
This change fixes the reading of coverage information to only read the
function name if it's present.

Make ParentMap work with explicit specializations of function templates.
For an explicit specialization, we first build a FunctionDecl, and then
we call SubstDecl() on it to build a second FunctionDecl, which has the
first FunctionDecl as canonical decl.
The address of an explicit specialization of function template used to be the
canonical decl of the FunctionDecl. This is different from all the other
DeduceTemplateArguments() calls in SemaOverload, and since the canonical decl
isn't visited by ParentMap while the redecl is, it also made ParentMap assert
when computing the parent of a address-of-explicit-specialization-fun-template.
To fix, remove the getCanonicalDecl() call. No behavior difference for clang,
but it fixes an assert in ParentMap (which is e.g. used by libTooling).

A number of improvements to decorator conditionals.
* Change the `not_in` function to be called `no_match`. This makes
it clear that keyword arguments can be more than just lists.
* Change the name of `_check_list_or_lambda` to
`_match_decorator_property`. Again clarifying that decorator params
are not always lists.
* Always use a regex match when matching strings. This allows automatic
support for regex matching on all decorator properties. Also support
compiled regex values.
* Fix a bug in the compiler check used by _decorateTest. The two
arguments were reversed, the condition was always wrong.
* Change one test that uses skipUnlessArch to use skipIf, to
demonstrate that skipIf can now handle more scenarios.

Remove expectedFailureWindows decorator.
expectedFailureWindows is equivalent to using the general
expectedFailureAll decorator with oslist="windows". Additionally,
by moving towards these common decorators we can solve the issue
of having to support decorators that can be called with or without
arguments. Once all decorators are always called with arguments,
and this is enforced by design (because you can't specify the condition
you're decorating for without passing an argument) the implementation
of the decorators can become much simpler

We were already not extending i1 return values on x86_64 after r127766. This
takes that patch further by applying it to x86 target as well, and also for i8

The ABI docs have been unclear about the required behaviour here. The new i386
psABI [1] clearly states (Table 2.4, page 14) that i1, i8, and i16 return

[Coverage] Fix crash when handling certain macro expansions
When handling 'if' statements, we crash if the condition and the consequent
branch are spanned by a single macro expansion.
The crash occurs because of a sanity 'reset' in popRegions(): if an expansion
exactly spans an entire region, we set MostRecentLocation to the start of the
expansion (its 'include location'). This ensures we don't handleFileExit()
ourselves out of the expansion before we're done processing all of the regions
within it. This is tested in test/CoverageMapping/macro-expressions.c.
This causes a problem when an expansion spans both the condition and the
consequent branch of an 'if' statement. MostRecentLocation is updated to the
start of the 'if' statement in popRegions(), so the file for the expansion
isn't exited by the time we're done handling the statement. We then crash with
'fatal: File exit not handled before popRegions'.
The fix for this is to detect these kinds of expansions, and conservatively
update MostRecentLocation to the end of expansion region containing the
conditional. I've added tests to make sure we don't have the same problem with
other kinds of statements.
